AUXELARY AIR NLET AND MIXNG CHBER.

Application filed Getober'?, 1922. Serial No. 593,141.

T 0 all wiom t may concern.'

county of Cook and State of illinois, have invented new and usefulimprovements in an Auxiliary Air lnlet and Mixing Chamber, of which thefollowing is a specification.

|This invention relates to a device or mixing air with the combustiblefuel used in an internal combustion engine, for increasing the powerderived from the uel, thereby permitting the obtaining oli' greatermileage per gallon o fuel, upon various makes of motor vehicles.

Another object of this invention is t provide a mixer, which iscontrolled from the dash or instrument board of the vehicle and islocated between the carburetter and the inlet into the cylinders, of aninternal conibustion engine, the said device comprising an air inlet,and a mixing lian operated by the suction created through the inlet fordrawing air into the inlet and thoroughly .iixing it with the fuelentering the cylinders.

Other objects of the invention will appear in the following detaileddescription taken in connection with the accompanying drawing wherein: y

Fig. 1 is a fragmentary side elevation of a motor vehicle showing theimproved mixer applied thereto.

Fig. 2 is a side elevation of the mixer.

`Fig. 3 is a vertical section through the mixer on the line 3 8 or Fig.2.

Fig. a is a cross section through the mixer taken on the line l4 of Fig.2.

Fig. 5 is a detail section on the line 5-5 Fig. 2.

Fig. 6 is a view partly in side elevation and partly in section oi amodilied form oi the invention.

Fig. 7 is a cross section on the line 7-7 of ig. 6.

Referrinmore particularly to the drawings, the improved gas equalizerand saver comprises a cylindrical body 1, which is open at one end andhas a rotary plug'2 rotatably mounted in the open end. transverselyextending connecting arm 3 is formed upon the plug 2 and is connected bymeans of the extension fi with a rod 5 which is adapted to be connectedto any suitable accelerating structure of the vehicle upon which thedevice is mounted. The cylindri-` cal body 1 is provided with an arcuateslot 6 adapted to permit air to enter the interior of the body, and theplug 2 is provided with a slot 7 adapted to register with the slot 6 topermit the entrance of air into the body, or to be moved out ofregistration with the slot 6 to cut off the' entrance of air. Theregulation of the registering portions of the slots 6 and 7 will-regulate the quantity of air drawn into or entering the body 1. A setscrew 8 is provided `ior limiting the rotary movement of the plug 2.

The cylindrical body 1 is connected by a fiat coupling 9 with atransversely extending cylindrical housing 10 which is connected to thecarburetter 11 and the intake manifold 12` of the engine 13 by means ofsuitable rivets, bolts or the lilre as shown at 14, which extend throughthe openings 15; in the attaching flanges 16. A mixing fan 17 isrotatably supported within the transverse housing 10 and is adapted tobe rotated by the suction created through the housing, by the entranceof the iuel into the cylinders and by the operation of the pistonstherein. The connection 9 is provided with a plurality of openings 18,which communicate with the interior of the body 1 and the housing 10 sothat the 'suction through the manifold 12 will draw air from the body 1into the housing 10 where it will be thoroughly mixed with the fuelbeing drawn into the manifold, by rotation oit the mixing fan 17.

ln Figs. 6 and 7 of the drawings a slight modilication of the invent-ionis shown and in this modiiied form, the housing 1 and cap 2 tends tohold the cap 2 in position to permit I full registration o the openings6 and 7.

Any suitable means may be connected to the eyelet 21 Jfor rotating thecap 2 to reduce the portions of the openings, in registration. ln themodified form, the connecting section 9 is provided with a flat slot 22which comf municates with a flat s101323 formed in the body 2li. Thebody 2d is positioned transversely to the body 1', as clearly shown inFig. 6 of the drawings, and it carries the housing 10 in which themixing fan 17 is rotatably mounted.

lt is, of course,'to be understood that the invention may be constructedin other manare connected by a spring 20, which ners and the partsassociated in dii'erent relations and, therefore, We do not desire to belimited in any manner except as set 'orth in the claim hereuntoappended. A

Having thus described our invention what We claim is:

A gas equalizer including a cylindrical body open at one end, a rotaryplug mounted in the open end of the body, said body and plug each havingan arcuate slot adapted to be moved into registering positions, meansconnected with the plug `for rotating the same to bring said openingsinto registering positions, a cylindrical housing at right angles to thebody, a flat engaging portion connecting the body and housing and havinga plurality of openings therein to provide direct communication betweenthe body and housing, and a mixing fan rotatably supported in thehousing.

In testimony whereof We ax our signatures.
